Parke, Herbert William; Wormell, Donald Ernest Wilson (1956): The Delphic Oracle, Blackwell, s. 3: «The foundation of Delphi and its oracle took place before the times of recorded history. It would be foolish to look for a clear statement of origin from any ancient authority, but one might hope for a plain account of the primitive traditions. Actually this is not what we find. The foundation of the oracle is described by three early writers: the author of the Homeric Hymn to Apollo, Aeschylus in the prologue to the Eumenides, and Euripides in a chorus in the Iphigeneia in Tauris. All three versions, instead of being simple and traditional, are already selective and tendentious. They disagree with each other basically, but have been superficially combined in the conventional version of late classical times.»
